| 摘要 |
The invention relates to an electrical contact coupling (3) for automatic central couplings or central buffer couplings for rail vehicles, especially for claw couplings equipped with a protective arm, a rotatable claw and with a drop latch of the "AAR" or "Janney" design or equipped with two rigid claws and claw latches of the "Willison" design comprising a contact support (8) which is fastened to the coupling head and which is guided in a longitudinally displaceable manner in a longitudinal direction of the central buffer coupling. An economical and flat-structured solution provided for constructing and configuring an electrical contact coupling (3) and an air line coupling (12) provided for a central coupling or central buffer coupling of the aforementioned type is characterized in that the longitudinally displaceable contact support (8) is arranged underneath and on a supporting unit (1) which, underneath the coupling head, is elastically supported by and fastened to the same such that at least one actuating cylinder (6) for longitudinally displacing the contact support (8) is arranged inside the supporting unit (1) and such that an air coupling (12) having an opening (11) is arranged on the supporting unit (1) in the coupling plane.
